38 * TEST IDENTIFIER : readlink02
40 * EXECUTED BY : anyone
42 * TEST TITLE : Basic test for readlink(2)
44 * PARENT DOCUMENT : usctpl01
52 * AUTHOR : William Roske
54 * CO-PILOT : Dave Fenner
56 * DATE STARTED : 03/30/92
58 * INITIAL RELEASE : UNICOS 7.0
62 * 1.) readlink(2) returns...(See Description)
64 * INPUT SPECIFICATIONS
65 * The standard options for system call tests are accepted.
66 * (See the parse_opts(3) man page).
68 * OUTPUT SPECIFICATIONS
71 * Terminates - with frequency and infinite modes.
74 * Uses SIGUSR1 to pause before test if option set.
75 * (See the parse_opts(3) man page).
81 * No run-time environmental needs.
83 * SPECIAL PROCEDURAL REQUIREMENTS
86 * INTERCASE DEPENDENCIES
89 * DETAILED DESCRIPTION
90 * This is a Phase I test for the readlink(2) system call. It is intended
91 * to provide a limited exposure of the system call, for now. It
92 * should/will be extended when full functional tests are written for
96 * Setup signal handling.
97 * Pause for SIGUSR1 if option specified.
100 * Loop if the proper options are given.
101 * Execute system call
102 * Check return code, if system call failed (return=-1)
103 * Log the errno and Issue a FAIL message.
104 * Otherwise, Issue a PASS message.
107 * Print errno log and/or timing stats if options given
